Overstress and flowstress approaches to dynamic viscoplasticity
Viscoplasticity is mostly modelled by the flowstress approach, where the flowstress (Y) is a function of pressure, temperature, plastic strain and strain rate Y(P,T, εp, ε̇). For dynamic Viscoplasticity the flowstress approach is used in hydrocodes together with the radial return algorithm, to deter...
